+# Dependency Review Action
+#
+# This Action will scan dependency manifest files that change as part of a Pull Request,
+# surfacing known-vulnerable versions of the packages declared or updated in the PR.
+# Once installed, if the workflow run is marked as required,
+# PRs introducing known-vulnerable packages will be blocked from merging.
+#
+# As recommended by Microsoft's security guidelines (https://docs.opensource.microsoft.com/security/tsg/actions/#requirements-for-security-hardening-your-own-github-actions), 
+# 3rd-party actions should be pinned to a specific commit hash to prevent supply chain attacks. 
+# This update aligns with best practices; 1st/2nd-party actions is not required hash pinning.
